BARREL-TAPPING DEVICE.

Specification of Letters Patent.

Fatented June 14, 1910.

Application filed April 6, 1909. Serial No. 488,157.

' T all whom it may concern:

ing or casing either in its opened or closed posltion when manipulatedby the coupling tube but which can be removed from the casing when in aposition intermediate of its open and closed positions to permit ofcleaning and pitching the barrel when it is empty.

In the accompanying drawings: Figure 1 is a vertical longitudinalsection of the taping device showing the valve open. Fig.

' 2 is a similar view showing the valve closed.

Figs. 3, 4 and 5 are transverse sections in the correspondingly numberedlines in Fig. 1, but showing different positions of the valve disk. Fig.6 is a detached section of the valve casing taken lengthwise of itsaxis. face view of the valve disk. Fig. 8 is a similar view of thecoupling tube. Fig. 9 is a cross section in line 99, Fig. 1.

Similar letters of reference indicate corresponding parts throughout theseveral views.

A represents the casing or bushing of the valve which is preferably ofcircular form and has an external screw thread a whereby the same issecured in an opening in the barrel. At its inner end this casing isprovided with a head B which has a port or passage 7) on one side of thecenter of the casing and on its bore the latter is provided with twocircumferentially extending looking ribs C, C between its outer andinner sides and a pair of stops or shoulders cl, (Z at the outer side ofthe casing. The opposing ends of the locking ribs are separated byintervening gaps or spaces 6, e and each rib is beveled or inclined onits inner side at opposite ends in opposite directions, as shown at f,7, Fig. 6.

G represents a valve disk or stopper which is arranged within the casingon the outer side of its head and provided with a port or passage 9.Upon turning the valve disk in one direction its port may be broughtinto line or register with the port of the casing head and the valve isopen, as shown in Figs. 1 and 3, while upon turning the valve disk inthe other direction, the solid part of the same is brought over the portof the casing head and the valve is closed, as shown in Figs. 2 and 4:.

For the purpose of making a liquid tight joint between the valve diskand casing both in its open and closed position, a packing is providedwhich preferably consists of a strip I of fiber or similar materialwhich is secured in a dovetail or undercut groove or seat 6 formedtransversely on the inner side of the valve disk, so as to cover thearea of the disk which is over the casing port both in the open andclosed position of the disk. The packing is provided with an opening 11in line with the port of the disk, so as to practically form acontinuation thereof.

Between its inner and outer sides the valve disk is provided on oppositesides of its periphery with laterally projecting locking lugs j, 7'which are adapted to pass through the gaps e, e in assembling or dismembering the valve and to engage with the inclined inner sides of thelocking ribs, as shown in Figs. 6 and 9, for holding the parts in anassembled condition and also tightening the disk on the casing with awedge action in its open and closed position.

On the outer part of its periphery the valve disk is provided with twoshoulders or stops 7c, 70 which are adapted to engage respectively withthe stops or shoulders d, d of the casing for limiting or arresting therotative or oscillating movement of the disk relatively to the casing.The stops 70, 70 d, al are so located relatively to each other that whenturning the valve disk fully in one direction or toward the left, thestops d, 70 engage and arrest the valve disk in such position that thesolid or imperforate part of the packing is over the port of the casingwhile upon turning the valve disk in the opposite direction or towardthe right until the stops d 70 engage, as shown in Fig. 3, then thevalve disk will be arrested with its port and the opening in the packingin line or register with the port of the valve casing. Upon turning thevalve disk for closing the i 1 ing the coupling tube to the disk thesame engage with the valve, its locking lugs engage with the pair ofinclines f at diametrically opposite ends of the locking ribs, wherebythe valve disk is pressed with its packing against the head of thecasing While upon turning the disk fully in the opposite direction thelocking lugs of other pair of inclines on the opposite correspondingends of the locking ribs, thereby again pressing the disk and itspacking against the head of the casing. The gaps e, 6 between thelocking ribs and the stops of the casing are so arranged relatively tothe locking lugs and stops of the disk that the lugs are in line withsaid gaps when the disk is in a position intermediate of its extrememovement in either direction, as shown in Fig. 5, which is determined bysaid cooperating pairs of stops on the casing and disk, therebypermitting the disk tobe applied to the casing or removed therefrom onlywhen it is neither open nor closed, but permitting of holding the sametight in the casing both in its open and closed positions so as to avoidleakage.

M represents the coupling tube of the tapping device which is adapted tobe secured to the valve disk with its passage in line with the porttherein, and L the tapping tube which is adapted to be pushed throughthe coupling tube and the ports of the valve disk, head and packing whenthe same are in line. A tight oint is produced between the coupling tubeand the valve disk when the same are coupled by means of a washer orpacking ring it of rubber or other suitable material arranged in anannular groove n at the inner end of the coupling tube around thepassage therein and bearing against the outer side of the valve diskaround the port therein.

Means are provided for permitting the valve disk to be turned into itsopen and closed position by the coupling tube and to hold said tube anddisk in coupled condition when turned in position for opening the valveand permit the tube to be applied to or removed from the disk. only whenthe latter is turned in the position which closes the valve.- For thispurpose the coupling tube is provided on opposite sides with two arms 0,0 which project inwardly and are provided at their inner ends withlaterally projecting locking lugs p, p and the valve disk is provided onopposite sides of its periphery with recesses or sockets g, g which areout of line with its locking lugs. While the valve disk is in its closedposition, its recesses g, g are opposite the gaps e, e respectively,between the locking ribs of the valve casing. In apply and easing itsarms are inserted in the recesses g, g of the disk and its locking lugs79, p are passed inwardly through the gaps e, 6 until the same are infront of the locking, ribs of the of the casing,

casing. Upon now turning the disk and the valve, the locking lugs of thetube move in front of the inner sides of the locking ribs as shown inFig. 1, so that the coupling tube is held in place on the disk and casewhile the valve is open, rendering it necessary to turn the disk backinto its closed position before the coupling tube can be again detachedfrom the valve.

As shown inthe drawings, this is accom plished by making the cooperatinglocking lug'j of the disk and the gap 6 of the casing wider than thecompanion lug j and gap 6 on the opposite side of the valveand alsomaking the cooperating arm 0 and plug. of the coupling tube and recess 9of the dis different in form from the companion arm 0 plug 79 and recessQ1 on the opposite side of the coupling tube and disk.

In order to enable the valve disk to be turned into intermediateposition in which its locking lugs are in line with the gaps e, e andpermit the removal thereof for cleaning and pitching, a separate key isprovided which is provided with arms corresponding to those of thecoupling tube, the arms of the key being however unprovided with lookinglugs, so that no int'erloclring with the ribs of the casing occurs whenthe key turns the valve'disk into its intermediate free position. v

It will be noted that my improved tapping To facilitate the assemblingof the disk,

device comprises comparatively few parts which are of simpleconstruction and can be produced at low cost, and the parts can bequickly assembled and dismembered for cleaning and sterilizing.
